The basic requirements for clamping device
Precision CNC machining parts Without damaging the work piece positioning accuracy and quality assurance process under the premise of clamping devices should be enabled to:
1. The size of the appropriate clamping force. It is necessary to ensure that the work piece in the whole process of its stable position vibration small but also so that the work piece does not produce excessive clamping deformation.
2. Technology is good. Precision CNC machining parts The complexity of the clamping device should be suited to the production of the Program to ensure production efficiency its structure should be kept simple easy to manufacture and maintenance.
3. Good use. The operation of clamping device should be convenient safe and labor-saving.
Third the basic Clamp
The original force into a clamping force through the clamping body to achieve.Among the many institutions in the clamping wedge oblique spiral and by their eccentric combination of the most common application of clamping.
(A) Wedge Clamp
Wedge used as components or transmission of the clamping device clamping body known as the Wedge Clamp.
Precision CNC machining parts Wedge clamping directly the oblique wedge of the self-locking conditions are:Wedge angle smaller than the work piece Wedge Wedge and folders between the concrete and the friction angle.
Namely: a f1+f2
In order to ensure a reliable self-locking manual clamping generally take a =6 °~ 8 °. Using pneumatic or hydraulic device drivers do not need the self-locking oblique wedge it is desirable to a =15 ° ~35 °.
Wedge clamp is simple in structure than by large self-locking features such as performance it is widely available.
